firefox security update (RHSA-2010-0782)

Original Release Date: November 16, 2010
Last Revised: June 21, 2013
Number: ASA-2010-321
Risk Level: Low
Advisory Version: 7.0
Advisory Status: Final

1. Overview:

Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox. Network Security Services (NSS) is a set of libraries designed to support the development of security-enabled client and server applications.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2010-3175, CVE-2010-3176, CVE-2010-3179, CVE-2010-3183 and CVE-2010-3180 to these issues.

A flaw was found in the way the Gopher parser in Firefox converted text into HTML. A malformed file name on a Gopher server could, when accessed by a victim running Firefox, allow arbitrary JavaScript to be executed in the context of the Gopher domain. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-3177 to this issue.

A same-origin policy bypass flaw was found in Firefox. An attacker could create a malicious web page that, when viewed by a victim, could steal private data from a different website the victim has loaded with Firefox. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-3178 to this issue.

A flaw was found in the script that launches Firefox. The LD_LIBRARY_PATH variable was appending a "." character, which could allow a local attacker to execute arbitrary code with the privileges of a different user running Firefox, if that user ran Firefox from within an attacker-controlled directory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-3182 to this issue.

It was found that the SSL DHE (Diffie-Hellman Ephemeral) mode implementation for key exchanges in Firefox accepted DHE keys that were 256 bits in length. This update removes support for 256 bit DHE keys, as such keys are easily broken using modern hardware. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-3173 to this issue.

A flaw was found in the way NSS matched SSL certificates when the certificates had a Common Name containing a wildcard and a partial IP address. NSS incorrectly accepted connections to IP addresses that fell within the SSL certificate's wildcard range as valid SSL connections, possibly allowing an attacker to conduct a man-in-the-middle attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-3170 to this issue.

Recommended Actions for System Products:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place; risk to Avaya's product and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as a product update is available or the recommended action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.

Mitigating Factors:

When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. When certain factors determine that the overall risk for a particular product to be set to Low, Avaya will place these factors in the following table:

Vulnerability Mitigating Factors
CVE-2010-3170 CVE-2010-3173 CVE-2010-3175 CVE-2010-3176 CVE-2010-3177 CVE-2010-3178 CVE-2010-3179 CVE-2010-3180 CVE-2010-3182 CVE-2010-3183 These vulnerabilities are rated a Low risk as firefox is not a critical application on IALX, MN and MSS and is not installed on AES, CM, Conferencing, IQ, Presence, SM, SMGR, SP, VP or the CS1000.

3. Avaya Software-Only Products:

Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.

In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.

Product: Actions:
Avaya Aura™ Application Enablement Services 4.x/5.x Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the AES application.
CVLAN Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the CVLAN application.
Avaya Integrated Management Suite (IMS) Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the IMS application.
